BRICK ROUGHER AND SANDER.

SPECIFICATION forming part of Letters Patent No. 567,542, datedSeptember 8, 1896. Application filed April 11, I896. $eria1 No. 587,206.(No model.)

useful Improvements in Brick Roughers and Sanders; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the ac companyingdrawings, and to the letters of reference marked thereon, which form apart of this specification.

This invention relates to certain new and useful improvements inbrick-machines-; and it has for its objects, among others, to provide animproved brick sander and rougher in which the main shaft is providedwith a crank-wheel and connections whereby the pusher is operated slowlyin pushing, but returned rapidly. I provide a mechanism operated fromthe main shaft for turning or edging the bricks after they have beenroughened and sanded. The doors which serve to edge the bricks areprovided with a space between the same and at their edges to preventcatching of and injury to the hands of the attendant should heaccidentally get his fingers between the doors or between the same andthe walls of the opening in which the doors are arranged. Theroughing-plates are adj ustably and detachably held in position, and thechamber for the sand and the sandtubes are capable of adjustment toregulate the amount of sand to be delivered, as circumstances mayrequire. I employ a hinged spring-actuated sweep for trimming the edgesof the bricks and for supporting and controlling the rougher.

I aim, further, at improvements in the details of construction of thevarious parts, as well as in the machine as a whole. I provide a guardfor preventing the bricks from falling over when they are turned oredged, and in case the bricks are not removed in time, but are therewhen the next two bricks come along, this guard, which is substantiallyV- shaped, will serve to prevent injury to the machine by cutting thebricks in two.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention in this instance resides in the peculiar combinations andthe construction, arrangement, and adaptation of parts,

all as more fully hereinafter described, shown in the drawings, and thenparticularly pointed out in theclaims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which Figurel is a side elevation of my improvedmachine. Fig. 2 is a vertical longitudinal section on the line 2 2 ofFig; 4. Fig. 3 is a detail in plan, with portions in section, showingthe mechanism for operating the doors that serve to turn or edge thebricks.

Fig. 9 shows the needle-bar and its needles.Fig. 10 is a detail of the plate employed on the platform to engage thebricks as they are turned on edge and which serves to prevent injury tothe machine in case the bricks are not taken away before another lot aredelivcred onto the platform. Fig. 11 is a plan, .and Fig. 12 a detail,of a modified form.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates thesupportingframe; B, the endless apron or belt, mounted to travel uponrollers a, the shafts a of which are mounted to travel or revolve insuitable boxes or bearings 19 onthe frame of the niachine. This belt orapron receives thebrieks as they come from the molds or machine by whichthey are formed in any well-known manner. This belt is designed totravel. in the direction of the arrow in Fig. 2. It derives its motionin this instance from the sprocket-wheel C, secured to the shaft of theforward roller, over which the belt travels, and this sprocket-wheel isconnected by the sprocket-chain C with the sprocket-wheel D on the mainshaft E. This latter shaft is designed to receive its motion from anysuitable source in any well-known manner. (Not shown.) The shaft E ismounted in suitable bearings or boxes on the frame. In this instance Ihave shown intermediate rollers 6, over which the belt travels, butthese need not always be present. The bearing of the rear shaft a isrendered adjustable by means of the screw-rods c, which are screwed intothe vertical portions of the brackets b and are provided withadjusting-nuts c, as seen best in Figs. 1 and 2.

F is a disk fast upon the extended end of the main shaft E and providedwith a crankpin j, which works in the elongated slot g of the arm G,which is fast upon and depends from the oscillating shaft G, mounted insuitable hearings in the opposite side portions of the frame, and fastto this shaft, one near each end, are the rods or levers H, to the upperend of which are pivotally connected, as at h, the push-bars H, whichpush-bars are connected at their other ends with the pusher I, the endsof which are provided with the pins or projections t, which are designedto travel in the cam-paths J, provided by the substantiallydiamond-shaped switch-plates j, one on each side of the machine, andeach pivoted near its center, as at j, and beneath which plates the saidpins are designed to travel in pushing the bricks forward, and overwhich plates the said pins travel in the backward movement of thepusher, as will be readily understood.

K is a spring, one for each switch-plate, and each attached at one endto its plate j to the rear of its pivot and its other end held in anysuitable manner in a lug or bracket 7.: on the vertical portion A of theframe, as shown in Fig. 1, to normally hold the rear end of the saidplate in its downward position by its compression.

The pusher has hinged thereto a pusherplate L by suitable hinges l, thepintle Z of which has coiled therearound a spring L, one end of whichbears against the acting face of said plate to hold it to its work, butallows the plate to yield and prevents injury to the machine or to thebrick or pusher in case a brick happens to come irregularly along thebelt.

M is a box designed to contain sand, from which it is fed or caused toflow through the tubes M, the lower ends of which are preferablyflaring, as seen in Fig. 2, the box being provided with a portion of itslid or cover hinged, as seen at m. The outlets from the box to the tubesare controlled by the movable gates or valves m, which are arrangedwithin the box and movable over the bottom thereof, as seen best in Fig.2. These gates or valves are operated by the handles m arranged upon theunder side of the bottom of the box and secured to the vertical pins Mto the upper ends of which the gates or valves are also fast, so that bymovement of these handles the valves may be moved to govern the flow ofsand from the box through the tubes. This box with its tubes isremovably supported above the plat-form N in the following manner: Neareach end of the box, to the under side thereof, is secured a plate N,the ends of which are bent downward, as seen best in Fig. 1, the endsthereof being provided with openings to receive the vertical posts 12,upon which are the nuts n, so that the box may be adjusted verticallywhen desired.

The sand-box is supported over the chamber O, and this chamber isprovided with the partitions 0, which have their front faces rounded, asshown, while at their rear ends they have the openings or chambers 0,open at the side, to discharge the sand into the compartments of thechamber, the two outer ones having the spring-plates O, urged inward bythe springs 0 around the rods 0 and the tension of the springs beingadjusted by means of the nuts 0 At the discharge end of the chamber 0are .the plates P, the upper edges of which are serrated, as shown, andthe plates are secured in any suitable manner in the transverserecess 13at the discharge end of the chamber, and which communicates by thepassage P with the spout Q, arranged beneath the opening in theplatform, which is closed by the doors soon to be described. Thispermits of the escape of the sand that is carried forward from thechamber into the said spout, and clogging of the machine by reason ofaccumulated sand is prevented.

On the tubes nearest the discharge end of the machine is secured thecross-bar Q, rendered adjustable by means of the elongated slots andbolts, and in suitable openings in this cross-bar are mounted to slidethe vertical rods or pins Q the lower ends of which are hinged to theupper faces of the sweeps Q the rear ends of which are pivoted on a rodq, supported at the lower ends of the tubes, as shown. Springs g aroundthese vertical rods serve to hold the sweeps down to their work, butallow them to yield when meeting an obstruction, as a hard substance inthe brick. The front ends of these sweeps carry serrated plates Q, asshown in Fig. 4, although I may sometimes employ in lieu thereof a bar gcarrying a plurality of needles as shown in Figs. 8 and 9. The plates Qare vertically adjustable by slots and screws or bolts, as seen in Fig.4.

R is an opening in the plat-form N at the discharge end of the machine,and R are two oppositely-movable doors hinged at opposite sides of thisopening, as shown best in Fig. 5. There is a space or opening 1" leftbetween the ends of the doors and the adjacent walls of the opening, aswell as between the adjacent edges. of the doors and between their op-IIO posite sides and the adjacent walls of the opening, as shown clearlyin Fig. 5. This is to prevent catching of and injury to the tingers ofthe attendant. These doors are designed to be operated simultaneously inthe following manner: ()n the main shaft E is a cam S, which is arrangedto act upon the under side of the arm S, which is slotted, as seen inFig. 3, and which is provided with the antifriction-roller 8, againstwhich the cam acts, the other end of this arm being fast on thetransverse shaft S supported in suitable bearings s, in which it isadapted to rock. These bearings are on the cross bar or portion A of theframe. This cam is ad justably mounted on its shaft, so that it can beadjusted to vary the throw of the arm as occasion may require. Fast onthe shaft S is another arm T, to the under side of which between itsends is pivotally connected, as at t, the depending rod T, which worksthrough an opening in the lug t on the cross portion A of the frame, asseen in Fig. 2, and around this rod, between the under side of the lugand a not i on the lower end of the rod, is a spring T The free end ofthis arm T has pivotally connected therewith, as at 75 the vertical armor bar T the upper end of which is guided in a guideway 25 in the crossportion A of the frame, as shown best in Fig. 6. Between its ends thisvertical bar is provided with the projection or pin T which is designedto work in the slots u of the arms U, the ends of which overlap, asshown best in Fig. 6, and the other ends of which are fast upon theoscillating or rocking rods or shafts U, extending lengthwise of themachine, one at each side thereof, as seen best in Fig. 3,

.and mounted in suitable bearings on the frame. The ends of these rodsor shafts nearest the discharge end of l the machine have fast theretothe arms U which extend inward toward each other, as seen best in Fig.4, and to the adjacent ends thereof are pivotally connected, as at u,the substantially vertically-disposed arms M, the upper ends of whichare pivotally connected with the under sides of the doors R, as seen inFig. 4;. a a

The spout Q is supported from the frame beneath the opening in theplatform in which the doors are hinged, as shown, and is provided withan adjustable extension Q having provision for its adjustment. Thisconsists of the links g pivotally suspended from the shaft g secured tothe side of the spout, and to the lower ends of these links or hangersare pivotally connected the ends of the yoke Q which embraces threesides of the extension and is pivotally mounted thereon, as at g and thepivots thereof work in the vertical slots Q in the lower end of thespout Q, as seen best in Fig. 4. The upper end of the extension issleeved over the lower end of the spout, and the yoke is provided with ahandle or lever portion Q, by means of which the extension may be movedon its pivot to raise it, so that a bucket or other receptacle g may beplaced thereunder .to catch the sand that passes through the openings inthe platform and save waste of the same.

W is an angle-iron which is secured to the platform in proximity to thedoors thereof and is designed to prevent the bricks from falling overwhen turned up or edged. There is one of these at each side of thedoor-opening, and each is substantially V-shaped with a rounded edge andis so constructed and arranged that if the bricks are not removed intime the following two bricks would force the first ones against this Vedge and cuttheni in two on the same and thus prevent injury to themachine.

With the parts constructed and arranged substantially as above set forththe operation is as follows: Motion being given to the various parts andthe bricks fed to or placed on the apron or be] t, which travels in thedirection of the arrow in Figs. 1 and 2, the levers H and push-rods Hareactuated through the medium of the crank-disk and its wrist-pin andthe slotted arm, the pins or projections on the ends of the pusherentering the grooves or ways beneath the switch-plates, and in thecontinued movements of the parts the said pins or projections are pushedto the utmost forward limit of the grooves, and as soon as the pins orprojections have passed the lower ends of the said plates the springs Kserve to force the upper ends of the plates up and their lower endsdown, so that in the continued movement of the crank-disk the pins willtravel up the upper faces of the said plates, compressing the springstill the pins free themselves from engagement with the plates and dropdown again to repeat-their travel upon the under side of the plates topush another. brick along to the sanding-chamber.

It is to be understood that the crank-disk and the other parts are sotimed that the bricks will be carried along by the belt or apron at justthe required intervals, so that by the time the pusher returns to itsnormal position after having pushed one brick into the sand-chamber thenext brick will have moved so as to be in front of the pusher to be inposition to be engaged by thesame. The first brick acted upon is pushedby the pusher into the sandchamber and there left until the next brickis forced against it by the pusher and forced through the chamberbetween the partitions thereof and through the sand that has droppedthereinto through the tubes connected with the sandbox and the sand ispartially rubbed off by the partitions and spring-plates 0, and as thebricks emerge from the chamber they are roughened top and bottom by therougherplates or the needles, when the latter are employed. As thebricks emerge from the chamber they are forced onto the doors B, afterwhich the said doors are turned on their hinges, so as to turn thebricks upon their edges, so that they may be more easily handled, thecam S being so timed and the connections being such that the doors areactuated at proper intervals to turn or edge the bricks and be back intheir places to receive the next bricks. The sand that follows thebricks out of the chamber is allowed to fall into the spout and fromthence into the receptacle provided to receive it.

Modifications in detail may be resorted to without departing from thespirit of the illvention or sacrificing any of its advantages.

The machine may be adapted for more or less bricks by varying the widthof the belt and the number of compartments in the sanding-chamber. InFig. 11 I have shown a platform adapted for a four-brick machine. Inthis form the inner partitions that rub the sand on the bricks arevibratory, as seen in Fig. 11 and in enlarged detail in Fig. 12, inwhich the sides of the partition Y are hinged at 3 and their ends turnedinward, as at 3 a plate or other device Y being provided to prevent toogreat separation or movement of the parts Y on their hinge, the innerfaces of the said parts being provided with pins or studs 31*, on whichis held the spring Y A plate 3 (shown by dotted lines) is held over thesaid spring by a pin or other means g and can be easily removed when itis desired to adj ust the tension of the spring. The outer partitionsare adjustably secured to the platform, as seen in Fig. 11, so they maybe adj usted for different-sized bricks. The partitions seen in Fig. 5are rendered adjustable by means of the slots S shown therein, andthrough which pass the screws or other means which secure them to theplatform. The support W is also adj ustably mounted in position, havingits base portion provided with a slot, as seen in Figs. 5 and 10.
